AMALGAMATO R.

SPECIFICATION forming part of Letters Patent No. 332,473, dated December 15, 1885.

Application filed October 15, 1885. Serial No. 180,011. (No model.)

To all whom it may concern:

Be itknown that I, MYRON J. AMIOK, a citizen of the United States, residing in the city of Portland, county of Multnomah and State of Oregon, have invented certain new and useful Improvementsin Amalgamators, which are set forth in the following specification, reference being had to the accompanying drawings.

My invention relates to that class of devices which are applied in saving the precious metals by amalgamation, more particularlyin saving fine gold contained in the black sands deposited on the sea-beach; and it consists in a certainimproved organization of mechanism herein described, by which the entire pulp or sand is immersed in the quicksilver, thereby causing amalgamation and the retention of the precious metals and quicksilver,while the refuse matter is allowed to overflow and pass off.

In the drawings, Figure l is an elevation of my amalgamator, partly in section. Fig. 2 is a top View; Fig. 3, an end view of the same, and Fig. 4 is a plan View with sluice and driv- 2 5 ing machinery attached.

The funnel-shaped cylinders A A,with open ports IVI at the bottom, are made of castiron or any other suitable metal. B B indicate pistons, made of wood or any other suitable material, of such size as to work freely in the upright or bottom parts of cylinders A. O O are reservoirs intended to hold the quicksilver used in the operation. D is a receptacle or settler intended to receive and retain particles of quicksilver that may escape from reservoir 0. E is a walking-beam connecting and working the two pistons and their appendages. F is the standard of the walkingbeam. G indicates guides to keep in place the pistons B, and H the stays to brace the structure, and to which guides G are attached. I? is the pulley-shaft and cranks to set the machinery in motion. S indicates the sluices, forked as shown, to bring in the material to be operated upon, and T is a swinging gate to control the flow of said material alternately to the respective cylinders. U is a flange or hood encircling each cylinder-port, and we tending to the center of reservoirs O, to conduct the pulp to the center of each column of quicksilver.

The operation of the amalgamating-machine is as follows: The pulp or material coming through the upper end of sluice S falls into one of the cylinders A, the piston of that cylinder being elevated, so as to let the pulp pass it and reach the quicksilver. When a suflicient quantity has deposited on the top of the quicksilver in that cylinder, the gate closes by means of crank Q, thereby allowing the pulp to flow into the other cylindef. At the same time, through the motion of the walking beam E, the piston of the cylinder first filled descends, displacing the quicksilver and forcing the pulp down and out through the ports M and into the reservoir 0 when it is at the bottom of the quicksilver. The pulp is then subject only to the action of gravitation and ascends with the assistance of aflow of water, which is combined with or is part of the pulp through the column of quicksilver, and overflows reservoirO into settler D. The opera tion is alternately repeated in each cylinder, and an equal amount of pulp is received and discharged alternately from each cylinder, 75.

making the operation continuous. The gate T is so regulated and the movements are so timed as to direct the feed into each cylinder at the time when its piston is up so that the pulp may pass under it.

Having thus described my apparatus,what I claim as new therein, and desire to secure by Letters Patent, is

1. In an amalgamator, the combination of the cylinders having funnels at their tops and ports M at their bottoms, their pistons, the reservoirs O, and the forked sluice S, with its gate, substantially as set forth.

2. In an amalgamator, the combination of the cylinders and alternately-operating pistons, a sluice adapted to feed each cylinder alternately, quicksilver reservoirs for the cylinders, and a receptacle or settler, D, sub stantially as set forth.

In testimony whereof I have hereunto sub- 5 scribed my name.

MYRON J. AMIOK.
